FEED-WATER HEATER.

SPECIFICATION forming' part of Letters Patent/KNO. 781,005, dated January 3.1, 1905. Application filed September 29, 1903. Serial No. 175,070.

To @ZZ whom it may concern:

Be it known that I, FRANK E. KEYES, a resin dent of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Feed-Water Heaters; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved boilerfeed, and more particularly to means for heating feed-water and supplying the same to the boiler, the object of the invention being to provide simple and efcient means whereby the water will be brought to the boiling-point before it islet into the boiler.

A further object is to avoid the use of a pump, inspirator, or injector and to avoid all use of exhaust-steam from an engine or pump,- and thus obviate the damagingeifects produced in the boiler by oil and grease coming from the exhaust-steam.

A further object is to produce a waterheater and feed for steam-boilers which shall be simple in construction, sure and accurate in operation, and which shall be effectual in all respects in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims. The accompanying drawing is an elevation showing an embodiment of my invention.

A represents asteam-boiler, and 1 the steamldome thereon. Supported upon and in close proximity to the boiler and its steam-dome, lby means of brackets 2, is a tank 3, which concoupling 4 with a'valve l0. A pipe l1 communicates at one end with the lateral duct 6 lin coupling 4 and at the other end with the communicates, by means of a pipe 17, ,with the supply-tank or hydrant, so that steam passing from the tank through said vent can be utilized to heat the water in the supply-tank before said water enters the tank or heater 3.

To permit dirt whichl may accumulate in the tank or heater 3 to be washed out, I provide a pipe 18, which communicates at its upper end with the bottom of the tank or heater 3 and at its other end with a sewer or` other place of discharge and is provided at a suitable point with a cock 19.

With the construction and arrangements of parts above described the water will be brought to the boiling-point in the tank 3. The water from the supply-tank or hydrant will be made to enter the tank 3 simultaneously with the steam, the steam entering throughthe'pipe 11 and coupling l1 also serving to assist the flow of water through pipe 8 and duct 5 of cou plingll into the tank 3. rIhus when the vent and pipe 17 are open water from the supply-tank will be injected into the tank or heater 3 by the steam from the steamdome passing through the pipe 11.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.

Having fully described my invention, vwhat I claim as new, and desire-to secure byLetters Patent, is- Y l. The combination with a boiler, a tank or heater, a pipe for conducting water therefrom to the boiler, and a source of water-supply, of

IOO

a pipe connecting the source of water-supply with the tank or heater, a pipe connecting the tank or heater with the steam-dome of the boiler, and a pipe Connecting the top of the tank or heater with the souree of water-su ppl y.

2. The combination with a boiler, a tank or heater, a pipe for conducting water therefrom to the boiler, and a source of Water-supply, of a coupling communicating with the tank or heater, said coupling having a Vertical duet and an inclined duet, a pipe connecting the Vertical duet With the source of water-supply,

a pipe connecting the inclined (hiet with the steam-dome of the boiler, and a pipe eonueeting the top ol the tank or heater with the source oi' water-supply.

In testimony whereof l have Signed this Speeilieation in the presence oi two sllbeerbing,` witnesses.

FRANK E. KEYES.
